CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a national stage application (under 35 U.S.C. §371) of PCT/EP2014/072629, filed Oct. 22, 2014, which claims benefit of European Application No. 13190652.1, filed Oct. 29, 2013, both of which are incorporated herein by reference in their entirety.

The present invention relates to the technical field of dyestuffs for dyeing and printing of hydroxyl- and/or carboxamido-containing material.

Acid dyes with pyridine couplers are known from prior art and can be used as colorants in different applications, see for example U.S. Pat. No. 3,959,250 A1, U.S. Pat. No. 5,468,848 A1, JP 1 197578 A and WO 2007/045825 A2.

However, in the context of the dyeing and printing of hydroxyl- and/or carboxamido-containing material the known dyes have a number of technical disadvantages, which require improvement.

One such disadvantage is, that many of them are comprising heavy metals such as Cu, Cr or Ni. Such heavy metals are critical from a toxicological as well as an environmental point of view and shall thus be excluded.

Surprisingly, it has now been found that the dyes of formula (1) as described below show highly advantageous properties over the known dyes. These include high tinctorial strength with high brilliancy as well as high fastness properties such as wash, contact and light fastness on the materials mentioned above, on blends containing them as well as on microfibres. Most importantly, dyes of formula (1) are substantially heavy metal free and provide dyeings that are levelled. Metals may only be present as counter ions and are selected from the groups of alkali and earth alkali metals, which do not have such effects as heavy metals.

If heavy metals are present at all in the dyes of the present invention they do not result from being integral part of the dye but are coursed by the production process in general. Reasons in general for these impurities can be impurities resulting from educts and catalysts being used in the respective reactions—the levels of such impurities can be managed and be kept well below those recommended e.g. by ETAD® and would thus be below 100 ppm for Cr, below 250 ppm for Cu and below 200 ppm for Ni just to mention the values for the metals mentioned above. This is a significant improvement as compared to dyes where such metals are present at molar levels.

The present invention refers to dyes of the formula (1) and mixtures thereof

Still another aspect of the present invention is/are: Fiber and blends containing such fiber selected from the group consisting of: synthetic fiber materials, nylon materials, nylon-6, nylon-6,6 and aramid fibres, vegetable fibres, seed fibres, cotton, organic cotton, kapok, coir from coconut husk; bast fibers, flax, hemp, jute, kenaf, ramie, rattan; leaf fibres, sisal, henequen, banana; stalk fibres, bamboo; fibres from animals, wool, organic wool, silk, cashmere wool, alpaca fiber, mohair, Angora fibre as well as fur and leather materials; manufactured, regenerated and recycled fibres, cellulosic fibres; paper fibres, cellulosic regenerated fibres, viscose rayon fibres, acetate and triacetate fibers, and Lyocell fibers comprising one or more dye(s) of the present invention either in chemically and/or physically bound form.

The above-mentioned substrates to be dyed can be present in various forms such as but not limited to yarn, woven fabric, loop-formingly knitted fabric or carpet. For instance in the form of sheetlike structures, such as paper and leather, in the form of films, such as nylon films, or in the form of a bulk mass, for example composed of polyamide and polyurethane, in particular in the form of fibers, for example cellulose fibers. The fibers are preferably textile fibers, for example in the form of woven fabrics or yarns or in the form of hanks or wound packages.

The dyes of the present invention and their salts and/or mixtures can be used as a single dyeing colorant in dyeing or printing processes or can be part of a di-, tri- or multi-component combination colorant in dyeing or in printing compositions. The di-, tri- or multi-component shade dyeings show similar fastness level as compared to dyeing performed with a single colorant component.

Dyes of the present invention and their salts or mixtures are highly compatible with other known and/or commercially available acid dyes and they can be used together with such dyes of related chromophores and similar technical performance to obtain specific hues. Similar technical performance includes: comparable build-up, comparable fastness properties and comparable exhaustion rates during dyeings.

The dyes according to the invention can be applied to the materials mentioned, especially the fiber materials mentioned, by the application techniques known for water-soluble dyes. This applies to both, dyeing and printing processes.

Useful surface-active substances include for example: all surfactants, preferably nonionic surfactants, butyldiglycol, 1,2-hexanediol.

The inks of the present invention may further comprise customary additives, for example substances to inhibit fungal and bacterial growth in amounts from 0.01 to 1% by weight based on the total weight of the ink.

The inks may be prepared in a conventional manner by mixing the components in water.

The inks of the invention are particularly useful in inkjet printing processes for printing a wide variety of pretreated materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and cellulosic fiber materials of any kind. Blend fabrics, for example blends of cotton, silk, wool with polyester fibers or polyamide fibers can similarly be printed.

In contrast to conventional textile printing, where the printing ink already contains all necessary chemicals, in digital or inkjet printing the auxiliaries have to be applied to the textile substrate in a separate pretreatment step.

The pretreatment of the textile substrate, for example cellulose and regenerated cellulose fibers and also silk and wool, is effected with an aqueous alkaline liquor prior to printing. In addition there is a need for thickeners to prevent flowing of the motives when the printing ink is applied, for example sodium alginates, modified polyacrylates or highly etherified galactomannans.

These pretreatment reagents are uniformly applied to the textile substrate in a defined amount using suitable applicators, for example using a 2- or 3-roll pad, contactless spraying technologies, by means of foam application or using appropriately adapted inkjet technologies, and subsequently dried.

The examples below serve to illustrate the invention. Parts and percentages are by weigh unless noted otherwise. The relationship between parts by weight and parts by volume is that of the kilogram to the liter.
